The measured absorbance of another sample was 0.09. Would you use the regression line to calculate protein concentration in that sample? Explain briefly.

Report the numerical value for the coefficient of determination. Use 2 significant figures. 

From the regression line report the value for the slope and intercept using 2 significant figures. 

Perform the test you chose in the previous question to compare BMI levels in individual with normal blood pressure vs. those considered prehypertensive. Report the p-value using 2 significant figures.

What’s the appropriate test statistic you will use to compare these groups? 

Generate a plot of the residuals. 

Use transformations to graph the given function.f(x) =  |x – 2| + 1

Solve the equation. Write the solution set with the exact solutions.ln x + ln(x – 3) = ln(3x – 5)

Find all the zeros. f (x) = x3 – 6×2 – 2x + 40

Sketch the function. f (x) = -x3 + 4×2
